Bathymetry, Borders, Piers and a Totem Pole

I was taking a look at various bathymetry in the northwest Washington coastal waters and noted a couple of things on this image: one of great past importance and the other of more recent attention.

  

I labeled the second image with Cherry Point and the border between US and Canada as a red line.

 

The past issue involving bathymetry is note the western side of the San Juan islands is bounded by a deeper channel than the east side of the islands. The United States demonstrated that western channel was the deeper channel and that ultimately determined the U.S.-Canadian border through the coastal islands in 1872 borderlines-and-oregon-country-whatcom. The line was drawn to include San Juan Island despite a strong previous presence by the Hudson Bay Company. 

The other more recent bathymetry is the relatively deep water right up to the coast at Cherry Point. That fact has caused that bit of coast to be an appealing location for deep water piers. Three already exist serving two refineries and an aluminum plant. And another is being proposed for shipping coal. But deep water close to shore also makes for very good fishing, and the local tribes are objecting to the scheme. 

On Friday I went out to Cherry Point right after my return from urban geology (another day for those stories). I arrived just in time to see the totem pole carved by House of Tears arrive from its recent visits to the Powder River and points between.

Big Landside Hints

Posting has been a bit limited of late due to field work and deadlines.

 

I visited a large slide area on Hood Canal recently. I had been to the same slide area a few years ago before it reactivated and identified a clay unit that is rather consistently associated with a number of deep-seated landslides in the area. With the more recent movement it really doesn't take a geologist to know something is amiss. Lots of obvious and not so obvious hints.

 

The first picture above shows a fairly mature cedar that is tilted well out of plumb. The road also has a bend where it crosses onto the failure area and has been off set from its original straight path. Note the thick growth of horse tail indicating wet soils at depth.

The fence has been off set about 15 feet as a block within the slide complex moved at a faster rate than another block.

Northern Alligator Lizard Habitat at Discovery Bay

This south facing shoreline bluff at Discovery Bay had abundant lizards. Initially I did not really notice the scurrying of the lizards as I walked along. It wasn't until afterwards their presence registered.

 

The habitat is the result of a number of factors. The site had a south aspect, is in the dry rain shadow of the Olympic Range, had extremely well drained sandy soils from recessional outwash gravel and sand and a frequency of slope failures that was not too extreme to wipe out the habitat, but maintained open areas, and a built up beach with lots of drift wood for hideouts. Alas, I was not quick enough to get any pictures once I realized what I was seeing. But still a great example of geology, climate and landslides creating a unique critical (for lizards) habitat.  burkemuseum.org/herpetology/reptile/northern_alligator_lizard

 

 

Ecology's Coal Scope Non Precedent

Washington State Senator Doug Ericksen's (R-42nd) sent a letter to the Washington State Department of Ecology expressing concerns about the scope of the Environmental Impact Statement for the proposed coal terminal in Whatcom County. His view reflects the views of many coal terminal supporters. The letter and reply from Ecology has generated some fairly typical posturing (washingtonstatewire.com/ecology-on-hot-seat-about-coal-port-analysis-business-calls-it-bizarre-worrisome/).

The primary concern is about precedent regarding these scope items Ecology is requiring for the review:

• A detailed assessment of rail transportation on other representative communities in Washington and a general analysis of out-of-state rail impacts.
• An assessment of how the project would affect human health in Washington.
• A general assessment of cargo-ship impacts beyond Washington waters.
• An evaluation and disclosure of greenhouse gas emissions of end-use coal combustion.

However, despite coal terminal proponents protestations, the scope of review Ecology is seeking may not really be all that much of a precedent in the larger picture of environmental impact statements for similar projects. A rail project from the Powder Basin to the upper Midwest was required to review transportation impacts and noise impacts. The initial EIS process assessed impacts to traffic and emergency vehicles and which led to a project mitigation requirement to have in place two new grade separated crossings to address emergency vehicle delays. (Note there was an interesting geology component to the rail routing in the EIS that led to expanding use of the existing rail line through potential traffic problem areas)

And upon appeal a limited further review of noise was required and a review green house gas emissions was required (ca8.uscourts.gov/opndir/03/10/021359P.pdf).

In the opinion the Court stated that indirect effects must be reviewed and that "Indirect effects are defined as those that are caused by the action and are later in time or further removed in distance, but still reasonably foreseeable. It is reasonably foreseeable - indeed, it is almost certainly true that the proposed project will increase the long term demand for coal and any adverse effects that result from burning coal. We believe that it would be irresponsible for the Board to approve a project of this scope without first examining the effects that may occur as a result of the reasonable foreseeable increase in coal consumption."

In the context of the similar scale coal terminal project at Cherry Point and the 8th Circuit opinion, Washington State Department of Ecology is being responsible. But not everyone agrees. 

Change in the Weather Music

I've been a bit hooked on First Aid Kit I think in part due to the weather change that is coming. Their song Emy Lou starts with the line "The bitter winds are coming in and I am already missing the summer". First Aid Kit are from Sweden so no where near the cold in western Washington as in essentially all of Sweden. That said, it will not be long and our northwest Washington temperatures will stop reaching 60 and we will have that long chilly stretch of weather that requires a bit of tolerance. The second line of the song is "Stockholm is cold, but I've been told that I was born to endure this kind of weather". 

Our winters are not severe, but we do go a long time with no warm weather. A cold front is moving in late today and another with wind on Sunday. We may get some more dry warm weather late next week so a little early fall warm still might be left.

Another First Aid Kit song that brings some nostalgia as well as a reminder of a current loved one has a wonderful line regarding what the living in the north is like, It always takes me by surprise how dark it gets this time of year". Our days are getting very rapidly short, but Sweden still beats us on that particularly in the north of the country.

Lummi Dry Dock and Island Mountains

Every September the Lummi Island ferry goes to dry dock for maintenance and very often repairs. In a past period I was always up on the latest hull repair costs to the old boat, but I had never experienced dry dock directly. I have had an ongoing project on Lummi so I had my chance recently. Passenger only ferry service is provided by the Salish Sea during dry dock. As I have been going walk on anyway the difference for me was how I had to park from the ferry landing on the main land side. 

 

On my walk back to the car, I had nice views of the two highest island peaks as a frontal system began to arrive.

Don't Know Much About Mushrooms

Jon Krakaeur, author of Into the Wild has an update on his theory on the death of Chris McCandles (http://www.newyorker.com/online/blogs/books/2013/09/how-chris-mccandless-died.html). Something to think about when it comes to western Washington wild food.

My wild food diet is rather restricted - particularly when it comes to mushrooms. I was reminded of that last week while coming across a fair number of wild mushrooms in the field. I have limited my mushroom consumption to only two kinds and suspect that I am missing out on a variety of others. I did sprinkle some cut up chantrelle mushrooms on my Sunday pizza, but otherwise I mostly find the sudden explosion of fall mushrooms as a nice surprise in the forest and I reminder of how little I know.
